Abstract

A monitoring camera sets ON or OFF of swing correction in accordance with setting information about whether or not the swing correction of an image (that is, captured image) captured by an image sensor is performed, and corrects swing by cutting out a part of the captured image based on a swing detected value of a vibration sensor in a case where the swing correction is set ON. The monitoring camera outputs the captured image while maintaining a state thereof in a case where the swing correction is set OFF.

Claims

1. A monitoring camera which is installed at a place at which swing is generated in a fixed surface itself, the monitoring camera comprising:

a body housing configured to be fixed to the fixed surface;

a vibration sensor that detects swing of the monitoring camera;

an image sensor that captures an image; and

a processor that performs swing correction by cutting out a part of the image captured by the image sensor based on a detected value of the vibration sensor,

wherein the processor sets ON or OFF of the swing correction in accordance with setting information about whether or not the swing correction is performed, and outputs the image captured by the image sensor when the setting information indicates that the swing correction is set to OFF; and

wherein the processor sets ON or OFF of the swing correction in accordance with a remote operation.

2. The monitoring camera according to claim 1, further comprising:

a pan housing supported to be pan-rotatable around a pan axis;

a supporting arm having a base end which is supported on one end portion of the pan housing to be rotatable around a first tilt axis which is separated from and intersects perpendicularly with the pan axis; and

a tilt housing having one end portion which faces the supporting arm and which is supported at a tip end of the supporting arm to be rotatable around a second tilt axis which extends in the same direction as that of the first tilt axis.

3. The monitoring camera according to claim 1, further comprising:

a light source that illuminates a capturing range of the image sensor; and

a light source lens disposed at a front of the light source, and wherein a light condensing rate of the light source lens is variable,

wherein when the swing correction of the image sensor is performed, the processor reduces the light condensing rate to be lower than that in a case where the swing correction of the image sensor is not performed.

4. The monitoring camera according to claim 2, further comprising:

a light source that illuminates a capturing range of the image sensor; and

a light source lens disposed at a front of the light source, and wherein a light condensing rate of the light source lens is variable,

wherein when the swing correction of the image sensor is performed, the processor reduces the light condensing rate to be lower than that in a case where the swing correction of the image sensor is not performed.
